How this works in your browser
Splitting uses pdf-lib in your browser to build new documents rather than cutting the original apart. For each range you specify, a fresh empty PDF is created and the relevant page objects are copied into it, carrying along the fonts, images and other resources those pages reference. Nothing is rendered to pixels at any stage, which is why the output is byte-for-byte as sharp as the source. When you split every page, JSZip bundles the resulting files into one archive in the browser so you are not left downloading them one by one.

Common ways to use Split PDF
Sending only the relevant section
Pull the three pages someone actually needs out of a long report instead of emailing the whole document.
Separating scanned documents
Break a single batch scan back into the individual invoices, receipts or forms it contains.
Getting under an attachment limit
Divide an oversized PDF into parts small enough to send when compression alone is not enough.
Frequently asked questions
Can I split every page into its own file?
Yes. Choose the "Split every page" option to get one PDF per page. All files are bundled into a ZIP for easy download.
What page range format should I use?
Use commas to separate sections and hyphens for ranges - for example "1-3, 5, 8-10". Spaces are optional. Pages are 1-indexed.
Does splitting reduce file quality?
No. Pages are extracted as-is using pdf-lib. No re-rendering occurs, so quality is identical to the original.
Why is each split file almost as big as the original?
Because PDFs share resources across pages. A font or logo used throughout the document has to be embedded into every file that needs it, so ten single-page PDFs can total more than the ten-page original. This is expected, not a fault.
Is my original file changed?
No. The source document is only read. Every output is written as a new file, so the original on your device is left exactly as it was.
What if I enter a page range that does not exist?
Pages outside the document are ignored rather than producing an empty file. Remember ranges are 1-indexed, so the first page is 1, not 0.
